Results on the Montreal Battery of Evaluation of Amusia (MBEA) are expressed as number of correct responses (average over the six sub-tests of the battery, maximum score = 30). Pitch Discrimination Thresholds (PDT) are in semitones. Data are reported as a function of group and groups are compared with t-tests. “NS” refers to a non-significant difference (p > 0.05) and standard deviations are in parentheses.
